The thicket of nanotubes in a VACNT electrode should operate like a cage to keep the silicon in check, says Pascal Boulanger, a physicist who helped found NAWA in 2013.

In 2014, scientists realized that tiny forests of carbon nano tubes can be used to make ultra black materials Unlike pigments, which absorb light, these nanotubes trap light in sort of molecular cages.

2014 年，家们意识管的微小束可以用来制造超黑色材料。与吸收光的颜料不同，这些管将光捕获在分子笼中。

Engineered materials like carbon nanotubes and diamond nano-threads seem like our best hope for producing materials strong and light enough for the job.

工程材料如管或钻石线最有希望，让我们能制造出够坚固又够轻盈、能胜任这个工作的材料。

Now, I notice you're using titanium. Did you give any consideration to carbon nanotubes? They're lighter, cheaper, and have twice the tensile strength.

我注意你用的是钛金属，你有没有考虑过用管，它们更轻更便宜，拉伸强度则是钛的两倍。

As for how to stiffen roads? Gregory says you could mix small amounts of synthetic fibers or carbon nanotubes into paving materials.

至于如何硬化道路？格雷戈里表示，可以将少量的合成纤维或管混入铺路材料中。

Similarly, Vantablack, the least reflective artificial material, traps photons in a forest of carbon nanotubes standing on their ends.

同样，Vantablack这种最不反光的人造材料将末端管丛中的光子困住。

However, more than 99 percent of Vantablack isn't made up of nanotubes — it's actually free space.

但事实上，99%的管黑体并不是由管构成的——其实就是自由空间。

Yet, nestling amid the quarks and transistors and the nucleic acids and nanotubes, there is a question.

然而，就在夸克、半导体、核酸和管等 涌现的同时，出现了一个问题。

But so far, we've only been able to manufacture very small nanotube chains.

但目前为止，我们能做出的管线非常小。

For the new application, the scientists added links to the circuit made of carbon nanotubes.

而对于这样一款新应用程序，家们在管制成的电线回路加上了链接。

The filter element he and his team have designed is a mesh of tiny carbon cylinders, known as nanotubes, and silver wires laid on top of a thin strip of cotton cloth.

崔教授及其团队所设计的滤水器元件采用微小的圆柱形网状物，也就是管。薄薄的棉布覆盖着管一端，并用银丝固定。

Each carbon nanotube, or CNT, is 10, 000 times thinner than a human hair — so small that photons, the tiny particles that make up light, can't get inside the tubes.

每个管，即 CNT，都比人类头发的万分之一还要细，它们实在太小，以至于构成光的粒子，也就是光子都无法进入其中。

Researchers at the Korea Advanced Institute of Science and Technology (KAIST) have developed an electronic ink made of liquid metal and very small tubes of carbon, or carbon nanotubes.

韩国高级技术研究所(KAIST)的研究人员已经开发出一种由液态金属和非常小的管或管制成的电子墨水。

The fuzzy structures in the feathers work like a cage for light, just like those carbon nanotubes.

羽毛中的模糊结构就像光的笼子，就像那些管一样。

First, they coated these with carbon nanotubes, to improve their conductivity.

首先，他们在这些木条子外面包上了，以提高它们的导电性。

The blackest carbon nanotube coating, developed by MIT engineers, traps 99.995% of light meaning that only 5 in 100,000 photons escape that forest of light-trapping nanotubes.

由麻省理工院工程师开发的最黑的管涂层捕获了 99.995% 的光，这意味着每 100，000 个光子中只有 5 个逃过了光捕获管束。
